| Summary: | An extensive
experimental programme tested an l-SEP unit with air and water.
This
provided data on the separation efficiency and pressure drop across the l-
SEP, as they varied with changing inlet conditions, geometry and outlet
restrictions.
The main conclusion from this work is that the resistance on
the outlets directly
affects the
efficiency of the separator. Although it is possible to optimise the
performance by changing 'the geometry, a small change in inlet conditions,
common in oil and
gas applications, causes the performance to change. _By
using an identified relationship between the differential pressure and the
operating conditions, an optimum performance over a much wider range of inlet
conditions can be achieved.
This work has contributed to the field of gas/liquid separation in axial-flow
cyclones by demonstrating that manipulating the differential pressure between
the outlets can control the
separation efficiency. The relationship developed
between the
optimum differential pressure and the inlet conditions has not been
identified in
any of the literature available at the time of this work.
